If you are looking for one time investment tracker you can go for this. But there are some cons1. App need much more modernization (wrt tracking and showing insights)2. Should include future prediction based on current and historical numbers3. Battery could be better too 8 days is nothing within tjis price range

Great screen-less tracker

2026-01-06    -Alex

I switched from a popular subscription based screen-less tracker and the polar loop does a great job with no subscription. Sleep tracking and hrv are on point and I found the activity tracking to be quite reliable as well although not perfect. The app is also decent and it does everything that it needs to do but a design refresh that’s coming soon will be much appreciated

Quite good. Feels light. You actually don't feel you are wearing anything.It's great for me as I don't really like wearing rings and watches too can be inconvenient for me. This fits snugly and metrices seems upto the mark. Been ten days since am wearing. No complaints yet

4.0 out of 5 stars Polar Loop: Is It Worth It?

2025-12-24    -Kisha

I ended up getting the Polar Loop faster through Amazon (about 3–5 days) compared to ordering directly from Polar. After waiting three weeks for my original order, I canceled it because the delivery timeline wasn’t clear, and communication was lacking.Setup was easy—the Loop connected quickly to the Polar app, which I already had from using other Polar watches. Tracking works well overall. However, battery life is shorter than expected; you’ll likely need to recharge every three days, and even that feels like a stretch. Another drawback is that it doesn’t clearly distinguish between general activity and exercise, so you may want to manually start workouts for accurate tracking.The biggest advantage? No subscription fee. That alone makes it worth considering. If you’re looking for a simple fitness tracker without ongoing costs, I’d recommend giving the Polar Loop a try.
